ToaZZ yu-mm it may conce/m.'

Be it known that lVILLiAM NiCHoLAs f Bonomi, a citizen ot' the United States, re-

siding at Dunlap. in the county of Grundy and State ot' Missouri, have invented certain new and useful Improvements in Shoekv Absorbers; and l do hereby declare the iol# lowing to be a full. clear, and exact description ot' the' invention, such as will enable others skilled'in the art to which it appertains to make and use the same.

This invention relates to shock absorbers and especially to shock absorbers for auto# mobiles and it has for its object the general in'iprovement 'of the construction and opera.- tion or" such devices.

With this object in view7 the invention consists in the improved construction, arrangement and combination of the parts hereinafter fully described and afterward specifically claimed.

l have illustrated an approved embodiment of my invention in the accompanying drawings in which the single ligure represents the invention in elevationi partly in section, showing means for attaching it to the frame and the axle of an automobile.

In the drawing 1 indicates the axle having a bushing 2 thereon with tlanges 3, ap-

proximately horizontal and having near.

. their edges suitable apertures or openings -l and 5 for the reception oi' the stay rods 6 and 7 which are retain-ed therein by enlarged heads 8. `A suitable plate 9, having similar apertures 1() and 11 registering with the apertures 4 and 5 is mounted upon the stay rods G and 7 in such manner as to support thereon a coiled shock-absorbing spring 12, the coils of which inclosc the stay rods 6 and 7. A plate llsimilar in construction to the plate 9 is mounted upon the upper ends of the stay rods (i and 7, being passed through suitable apertures 1-t andffl in said plate lil for this purpose and said plate 13 is locked upon said stay rods by means of heads 16. This plate 13 holds the spring 12 between it and the plate 9. Suitable apertures 17 and 1'8 are formed in the plate 9 adapted for the receptionot other stayl rods 19 and 20, the heads 21 ot' these stay rods being enlargedl to prevent their displacement from the plate 9. These stay rods pass through suitable apertures 22 and 23 in the plate 13 in such manner as tio allow said plate to slide or reciprocate on said stay rods. The en ds of the stay rods 19 and 20 are ,passed through suitable apertures 2l and 2o 1n a yoke 26, the heads 2T thereof being enlarged to retain said stay rods within the yoke. An aperture 28 is centrally formed in said voke and is adapted to loosely seat a swivel bolt 29, having an enlarged head 30 to prevent the same from passing through said aperture.

A sleeve having the interior upper end portion thereof threaded as indicated at 33 is mounted over the swivel bolt 29 and has oppositely disposed apertures 34 and 35v which register with a bore 31 in bolt 29 so that a rivet 36 passed through them will fasten the sleeve 32 to the swivel bolt in ittA such manner as to prevent longitudinal play butto permit swivel action.

A goose neck holt 37 having a threaded end 38 is threaded into the upper portion of the sleeve 32 and is locked in position by means ot' a lock nut 39. The opposite end of the goose neck bolt 37 is enlarged as at 40 and has an aperture 41 therethrough adapted to seat a connecting bolt 42, which' carries a channel connecting 'member 43 adapted to be suitably fastened upon the frame of a vehicle.

Previous to the riveting of the sleeve 32 upon the bolt 29, said sleeve 32 is adjusted upon the goose neck bolt 37, being turned for this purpose by a key inserted in suitable apertures 44 and 45, the lock nut 39 then being threaded home and.the rivet 36 secured in place. l

ln' operation my assembled device is mounted between the' axle and the-body or frame of an automobile or other vehicle in such manner that the spring 12v/'ill bewunder a continuous' tension so that the same will always absorb the shocks received when the vehieie is running. This operation causes tlnr pla-te 9 to slide over the stay bolts G and i' and the plate 13 to slide over the stay bolts 19' and 20. A l

Having now described my invention what I claim as new and desire to seclne'l by Letters Patent is r 1. A shock' absorber comprising Ineens for connecting-it to the axle of an. automobile,

adjustable 'means for connectingitl't the frame or body of an automobilefalyoke swiveled to the body connections; a pair ot" i rst n'ienvtioned plate, a second pair of rods slida'lily mounted through the two plates,

and a coil spring mounted lietu'een the two plates.

' slxoeli absorber comprising a pluralit)y of stay rods, a plurality of plates con,-

neeting said stay rods, a coil shock absorbing spring mounted between said plates and encircling a portion ot' said stay rods, a yoke mounted upon the opposite end of a portion of said stay rods haring a circular aperture: theretltrough7 a lSwivel bolt mounted tln'oughsaid aperture, a sleeve riveted to ,said swivel bolt in such manner as to allow swivel play thereof7 a goose neel; bolt adjustably threaded into Said sleeve, locking means locking'said goose neck bolt to said sleeveand connecting; means upon the opposite end of said'ooe neel: holt adapted to attach the same to the body of a vehele.

lamme v'threaded into said sleeve. lookingr means locking! saidmlast 4mentioned member to Said sleeve, and connecting' means upon the op,-

posite end ol" said adjuxtahle memlaer adapt ed to connect tliesanle to tlie body of a relncle.
